  • The Sun to the Earth—and Beyond: A Decadal Research Strategy in Solar and Space Physics is the product of an 18-month effort that began in December 2000, when the National Research Council (NRC) approved a study to assess the current status and future directions of U.S. ground- and space-based programs in solar and space physics research. The NRC’s Space Studies Board and its Committee on Solar and Space Physics organized the study, which was carried out by five ad hoc study panels and the 15-member Solar and Space Physics Survey Committee, chaired by Louis J.

  • For thirty years or more the expressions “Correlation of the Physical Forces” and “The Conservation of Energy” have been common, yet few persons have taken the necessary pains to think out clearly what mechanical changes take place when one form of energy is transformed into another. Since Tyndall gave us his book called Heat as a Mode of Motion neither lecturers nor text-books have attempted to explain how all phenomena are the necessary outcome of the various forms of motion.

  • Physics has an important role in our life. Without physics and the work of physicists, our modern life would not exist. Using physics, people created machines, instruments and some different divices from the crudest to the most modern aspect. Techology is developed more rapidly, more modern day by day. Moreover, all other natural sciences- example chemistry, biology, medicinedepend upon physics for the foundations of their knowledge.

  • "Show me a man who makes no mistakes, and I will show you a man who has done nothing."—LIEBIG. In this little volume the author gives but his own personal opinions upon the subjects discussed, and although the sentiments are expressed with an assurance born of conviction, yet he claims not infallibility. He has ever been unable to accept the usual explanations of the great physical forces; and the inadequacies of mooted theories have impelled him to efforts for more philosophical interpretations.

  • Geoinformatics is the science and technology of gathering, analyzing, interpreting, distributing, and using geospatial information. It encompasses a broad range of disciplines brought together to create a detailed but understandable picture of the physical world and our place in it. The Handbook of Research on Geoinformatics is the first reference work to map this exciting interdisciplinary field, discussing the complete range of contemporary research topics such as computer modeling, geometry, geoprocessing, and geographic information systems.

  • This is an exciting time for professionals associated with physical activity and the health professions. We have seen a substantial increase in the amount and type of research being conducted. Qualitative research has grown in popularity and has gained respect as a viable method of answering important research questions. Despite its broad appeal and inclusion in many disciplines, however, qualitative research often has an ethereal or mystical feel to it, particularly for those practitioners with strong roots in physical activity and the health professions.

  • Silicon technology continues to progress, but device scaling is rapidly taking the metal oxide semiconductor field-effect transistor (MOSFET) to its limit. When MOS technology was developed in the 1960's, channel lengths were about 10 micrometers, but researchers are now building transistors with channel lengths of less than 10 nanometers. New kinds of transistors and other devices are also being explored. Nanoscale MOSFET engineering continues, however, to be dominated by concepts and approaches originally developed to treat microscale devices...

  • Dramatic progress has been made in all branches of physics since the National Research Council's 1986 decadal survey of the field. The Physics in a New Era series explores these advances and looks ahead to future goals. The series includes assessments of the major subfields and reports on several smaller subfields, and preparation has begun on an overview volume on the unity of physics, its relationships to other fields, and its contributions to national needs.

  • Cyber-physical systems (CPSs) are an emerging research topic born from the ever increasing complexity of engineered systems. Future systems will have to interact with each other and with the physical world in a very tight and well coordinated fashion, and designing such systems is the research challenge behind CPSs. CPSs have been defined as “computational thinking and integration of com putation around the physical dynamic systems where sensing, decision, actuation, computation, networking, and physical processes are mixed”.
